The mining and coal washing industries involve extensive solid-liquid separation processes, where efficient management of tailings and process water is critical for both economic viability and environmental responsibility. Polyacrylamide (PAM) plays an indispensable role in these operations as a high-performance flocculant. NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier of PAM, highlights its significant contributions to these sectors.

PAM's Role in Mining Operations:

In mineral processing, PAM is used across several stages:

  • Tailings Thickening: After valuable minerals are extracted, the remaining slurry, or tailings, must be managed. PAM acts as a flocculant, accelerating the settling of fine solid particles in thickeners. This allows for clearer supernatant water to be recovered and reused, reducing the demand for fresh water and minimizing the volume of tailings that need to be stored. Anionic PAM is often preferred here due to the negatively charged nature of many mineral fines.
  • Filtration Aid: PAM improves the filtration rate of mineral concentrates and tailings by creating larger, more permeable flocs, reducing cycle times and increasing throughput.
  • Mineral Flotation: In some flotation processes, PAM can be used as a depressant or collector aid to selectively enhance the separation of desired minerals from gangue.

PAM in Coal Washing:

Coal washing plants generate significant volumes of fine coal particles and coal fines in their effluent (coal slurry). PAM is crucial for:

  • Centrifugal Separation: PAM enhances the separation efficiency of fine coal particles in centrifuges, improving the recovery rate of saleable coal and producing a drier filter cake.
  • Slurry Thickening and Filtration: Similar to mining tailings, PAM promotes the settling of coal fines in thickeners and aids in the filtration of coal washery underflow, allowing for water recycling and efficient management of waste streams.
